Cordless lawn mowers have reached the point where most UK gardens no longer need petrol. They’re quieter, easier to start, and far simpler to live with — especially on the damp, uneven lawns common across Britain.
The real advantage isn’t just convenience. It’s flexibility. You can mow early without upsetting neighbours, stop when the weather turns, and avoid dealing with fuel, fumes, or stubborn pull-cords altogether.
In this guide, we compare the best cordless lawn mowers UK gardeners can buy in 2026 — from affordable models for small spaces to more powerful options suited to larger lawns. We’ve assessed real-world performance, battery systems, and long-term ownership value to help you choose the right one.

Quick Comparison
The quick comparison below shows how each mower differs in cutting width, battery system and garden size suitability.
Best Budget Option
A lightweight cordless mower suited to small, regularly maintained UK lawns. The Einhell GE-CM 18/33 Li keeps things simple — easy handling, straightforward controls, and enough power for weekly cuts without pushing the price up.
In normal conditions, it delivers neat, even results and manoeuvres well around borders and tighter spaces. At just 11 kg, it’s also easy to lift into a shed or garage — something many budget mowers overlook.
It’s less suited to long or damp grass, where the single 18V setup can struggle. But for lawns kept under control, it offers dependable, affordable performance.
Key Features
- 18V Li-ion battery (4.0Ah typical)
- 33 cm cutting width
- 5 cutting height positions
- 30 L grass box
Best for: Small lawns up to 200 m²
Why buy: Affordable, lightweight, and part of a large shared battery system.
Why skip: Not ideal for thick, overgrown or damp grass.
Worx WG737E – In-Depth Review
The Worx WG737E is designed for medium-sized UK lawns where you need reliable cutting power without stepping into premium-brand pricing. Its 40V setup (two 20V PowerShare batteries) delivers consistent torque for regular weekly mowing, even on thicker seasonal growth.
In real-world use, it handles uneven patches and typical British grass conditions without fuss. The 37 cm deck is well suited to fenced suburban gardens, offering a good balance between coverage and manoeuvrability.
Because it’s part of Worx’s PowerShare system, the same batteries can be used across compatible strimmers, hedge trimmers and other garden tools. If you’re building a cordless setup over time, that flexibility makes long-term ownership more economical.
Key Features
- Dual 20V batteries (40V combined)
- 37 cm cutting width
- 6 cutting height settings (20–70 mm)
- 30 L grass collection box
- Foldable handle for easier storage
Best for: Medium UK lawns (300–500 m²)
Why buy: Strong balance of performance, run-time and battery ecosystem flexibility.
Why skip: Heavier than entry-level 18V models and more than small lawns typically require.

Tester’s note: We’ve used the Worx WG737E for over a year on a larger-than-average UK lawn with uneven patches and seasonal growth. It’s handled regular mowing without fuss.
Best Premium / Large Garden
If you want the most powerful mower on this list and budget isn’t the main concern, the Makita DLM432Z delivers the strongest cutting performance here. Its twin 18V LXT battery setup (36V combined) provides petrol-like torque without the noise, fumes or maintenance.
The wider 43 cm deck makes it more efficient on larger lawns, reducing the number of passes needed compared to 33–37 cm models. In typical UK conditions, it’s best suited to larger gardens of up to 575 m², especially where grass can grow thicker or more uneven.
Because it runs on Makita’s professional-grade LXT system, it’s also part of one of the most extensive cordless tool ranges available — making it a strong long-term investment if you already use Makita tools.
Key Features
- Twin 18V batteries (36V combined)
- 43 cm cutting deck
- 13 height settings (20–75 mm)
- 50 L grass collector
Best for: Larger lawns (500-575 m²) where cutting power and deck width matter most.
Why buy: Strongest cutting performance in this guide and compatible with Makita’s extensive LXT tool range.
Why skip: Often sold as a bare tool — batteries and charger may need to be purchased separately.
⚠ Buyer warning: The Makita DLM432Z is frequently sold as a bare unit. If you don’t already own Makita LXT batteries and a charger, the total cost rises significantly once added. It offers excellent value mainly for those already invested in the Makita ecosystem.
Best Compact / Small Space
For very small UK lawns and tight urban spaces, the Bosch CityMower 18V-32 keeps things simple. It’s lightweight, quiet, and easy to manoeuvre — making it well suited to courtyards and compact gardens where storage space is limited.
It runs on Bosch’s Power for All Alliance battery system, meaning the same 18V battery can be shared across compatible Bosch, Gardena and select Flymo tools — a practical advantage for smaller sheds.
In real UK conditions, it’s best suited to lawns under around 200–300 m² (depending on the exact 18V-32 model variant) . It’s not designed for tackling long or neglected grass, but for regular, light mowing in compact spaces, it delivers neat results with minimal effort.
Key Features
- 18V Power for All battery system
- 32 cm cutting deck
- ErgoFlex handles for improved comfort
- 3 height settings
Best for: Lawns under 300 m² and small urban gardens.
Why buy: Lightweight, compact and easy to store.
Why skip: Limited power and run-time for thicker or overgrown grass.
Honourable Mention
If storage space is your biggest constraint, the Flymo SimpliStore 340 Li earns its place on this list. It folds flat for compact storage, making it ideal for sheds, cupboards, and smaller garages where space is limited.
This isn’t a power-focused mower. Instead, it’s built for light, regular mowing on small to medium UK lawns that are already kept under control. For quick weekly cuts, it’s simple to handle and easy to manoeuvre.
Unlike Bosch or Makita, it doesn’t sit within a large shared battery ecosystem — the 18V battery is Flymo-specific — so it’s best suited to buyers who just want a straightforward standalone mower rather than building a cordless tool system.
Key Features
- 18V Li-ion battery
- 34 cm cutting width
- Folding handles for compact storage
- Central height adjustment
Best for: Quick weekly cuts on small to medium lawns.
Why buy: Excellent for tight storage spaces and simple, fuss-free mowing.
Why skip: Limited battery compatibility and not designed for heavy or overgrown grass.

🌿 How to Choose the Best Cordless Lawn Mower for Your Garden
When choosing the best cordless lawn mowers UK buyers can rely on, focus on the practical stuff that affects real mowing — not headline specs.
1) Match the mower to your lawn size
Be realistic about lawn size in everyday UK conditions (damp grass and uneven patches reduce real range).
- Very small lawns / courtyards (up to ~200–300 m², depending on variant) → Bosch CityMower 18V-32
- Small lawns (up to ~200 m²) → Einhell GE-CM 18/33 Li
- Medium lawns (around ~300–500 m²) → Worx WG737E 40V
- Larger lawns (up to 575 m²) → Makita DLM432Z 36V (best when you want more cutting power and a wider deck)
Tip: If your grass gets long, raise the cutting height and mow in stages. Cordless mowers cope far better when they’re not asked to take everything in one pass.
2) Check battery capacity (Ah)
Battery capacity matters just as much as voltage.
- Higher Ah = longer run-time
- For many UK gardens, 4.0Ah+ helps you avoid stopping mid-cut
- Long/wet grass drains batteries faster than you’d expect
3) Think about battery ecosystems
If you plan to buy other cordless tools (strimmer, hedge trimmer, blower), picking a shared battery platform can save money and storage space.
- Worx PowerShare
- Einhell Power X-Change
- Bosch Power for All Alliance
- Makita LXT
4) Storage and weight matter more than people think
If you need to lift the mower into a shed, cupboard or garage:
- Lighter models (Bosch / Flymo) are easier to live with
- Fold-flat handles make a big difference in smaller UK homes
🌻 Final Thoughts
Cordless lawn mowers have matured to the point where most UK gardens no longer need petrol power. Modern battery models are quieter, cleaner, and far easier to live with — while still delivering a neat, even cut.
For most medium-sized UK gardens, the Worx WG737E strikes the best overall balance of power, run-time and price.
If you’re working with a smaller lawn and want excellent value, the Einhell GE-CM 18/33 Li remains one of the most sensible entry points.
For larger lawns or thicker grass where cutting strength and deck width matter most, the Makita DLM432Z offers the strongest performance in this guide.
If storage space is limited, the Bosch CityMower 18V-32 or Flymo SimpliStore 340 Li are lightweight, easy-to-handle options designed for compact UK gardens.
Whichever model you choose, switching to cordless mowing makes garden care quieter, cleaner, and significantly easier — without sacrificing results.

⚡ Best Cordless Lawn Mowers UK – Frequently Asked Questions
Do cordless mowers work on damp grass?
They can, but you’ll get the best results once the lawn surface is mostly dry. Wet grass drains batteries faster and can clog the blades.
How long do the batteries last?
Most modern lithium packs provide 30–45 minutes per charge and last 3–5 years with proper care.
Can a cordless mower cut long grass?
Yes, but it’s best to raise the cutting height first and mow in stages. Most cordless models cope well if the grass isn’t damp or over 15 cm long. For overgrown lawns, a strimmer pass first helps prevent clogging.
Are cordless mowers powerful enough for large lawns?
Modern 36–40 V systems such as Worx PowerShare and Makita LXT easily handle 300–500 m² gardens. The key is using high-capacity batteries (4.0 Ah or higher) and keeping blades sharp for efficient cuts.
How many square metres can a 4.0Ah battery mow?
Rough guide: ~100–150 m² per 18–20V 4.0Ah pack in average conditions. Wet/long grass reduces this; sharp blades increase it.
